Inflation Rise Triggers More Wall Street Jitters

The Consumer Price Index, which measures how quickly prices are going up in the U.S. economy, rose at a faster than anticipated 2.1 percent in January compared to a year ago, triggering fears of another rocky run on Wall Street.

The monthly Labor Department report on the price of everything from gas to groceries was closely watched Wednesday, with Wall Street investors suddenly very concerned about inflation.

The stock market sell-off earlier this month that caused the Dow to fall over 1,000 points in a single day began after a Labor Department report showed wages grew at a better-than-expected pace in January.
